The role of T1 perfusion-based classification in magnetic resonance-guided high-intensity focused ultrasound ablation of uterine fibroids

To comparatively evaluate the role of magnetic resonance (MR) T1 perfusion-based time–signal intensity (SI) curves of fibroid tissue and the myometrium in classification of fibroids for predicting treatment outcomes of high-intensity focused ultrasound (HIFU) treatment. The fibroids of 74 women who underwent MR-HIFU treatment were classified into group A (time–SI curve of fibroid lower than that of the myometrium) and group B (time–SI curve of...
